Is it normal for voltage to drop under load?

Is it normal for voltage to drop under load?

Yes, Voltage drops when the load needs more current but that is not always true. there are 2 types of circuits, Constant Voltage circuit (CV) and. Constant Current circuit(CC).

Why is the crank on my Ford Focus not working?

Very common problem in this model because Ford decided to paint the grounding points in the chassis and didnt clean them before installing the grounds back! Its the 8mm bolt right by the battery. Its close to the top right corner by the firewall welded to the strut tower.

What causes engine rpm to drop at stop light?

engine rpm drops or stalls at stop light on abrupt braking. Hi there. In many cases, the issue you’re talking about is caused by an ignition timing problem; typically related to a damaged crankshaft position sensor or trouble within your ignition system such as the coil or distributor.

What does the voltmeter say on a focus?

After 180K miles it’s time for a new starter anyways, so replaced starter. Still nothing. So I started at the other end. Voltmeter shows ~12v at power into ignition, and the same on the gray/black wire after turning the key to start.

What’s the charge voltage on a Honda focus?

I checked battery voltage when I got home an hour later and battery was 12.4 v . assumed something was left on and drained the battery. I decided to use the car myself the next morning , put the gauge panel in test mode and monitored voltage while driving. 14.7 to 15.3 volts .I confirmed this voltage at the battery posts.

How many volts does a focus alternator have?

Started her up and I have the same high voltage output, 15.2 v @ idle ( measured at battery posts and gauge cluster) with no electrical loads and 13.1 v with as much electrical load as I can put on . At this voltage I will cook another lead acid battery.

Is it normal to charge a focus at 15 volts?

Normal charging on these is 14.5 to 15 volt, any meter could vary enough to get the 15.2. Meaning no problem. These charge heavier than the old days of 13.5 -14. Old battery may have been the problem but one thing for sure, if battery dead try to charge it up as these put out so much charge they commonly toast alt trying to bring up a dead battery.

Why is my Honda focus not cranking up?

If the battery measures anything less than 12.3 volts it is low enough to cause this issue, and the battery is the most common cause of this problem. And if it won’t pass a load test then even a higher amount will still fail to crank the car periodically. Just like the rest of America, one more that thinks 12 volts is enough to crank a car. WRONG.
